摘要
磷是农业和工业生产中重要的资源,但由于工业生产和生活污水排放了大量的磷到自然界中,导致水体富营养化等环境问题。污水中磷资源回收的常规方法有化学沉淀法,生物法以及吸附法。文章综述了磷酸根吸附材料的最新研究情况,探讨和评价了各种吸附材料的性能,最后讨论了未来研究的趋势和热点。
Phosphorus is an important resource for agriculture and industry. However, much of the phosphorus was discharged into water bodies with industrial wastewater and domestic sewage, which was partly responsible for eutrophication. Chemical sedimentation, bi- ological treatment as well as adsorption are usually used for removal of phosphorus from wastewater. Progress of the adsorption material of phosphate was summarized, the function of different adsorbing materials was discussed. The future research trend and hotspot problems were also discussed at the end.
